      Remove ONE_SIDED_COMPOUND experimental flag · c01dddb7
      Zoe Liu authored
      Always assume ONE_SIDED_COMPOUND is true as it has been adopted
      officially. Further, this patch also fixes the cmake setup for
      the experiment of EXT_COMP_REFS, as when EXT_COMP_REFS is on, it
      shall always have ONE_SIDED_COMPOUND on (but that was not the case
      without this patch).
      
      We leave EXT_COMP_REFS for the time being, even though it is also
      adopted, since by keeping this flag, it may allow its turning off to
      tune the encoder speed. The experiment of EXT_COMP_REFS should be
      removed eventually at the closing of the bitstream.

      Revert "Turn on the max_tile experiment" · 81d458b2
      Yaowu Xu authored
      This reverts commit ab8bb8b8.
      
      The reverted breaks many nightly run tests, reverting this temporarily
      to allow nightly tests to detect other failures. Once the issues are
      fixed, we can reenable the change in the reverted commit.

      Turn on the max_tile experiment · ab8bb8b8
      Dominic Symes authored
      max_tile was provisionally adopted at the working group meeting 2017-Oct-10
      
      This patch also enables support for 64x64 and 128x128 superblock size for max tile
      (rather than assuming 128). There is also one fix for max_tile in combination of
      loop restoration where the width/height was in the wrong units for max-tile specific code.

      Simplify tx_mode frame level bit · 923b73d8
      Debargha Mukherjee authored
      Adds a new experiment to simplify the tx_mode symbol.
      
      The existing frame level tx_mode information is converted to a single bit
      to select between largest tx_size for a prediction unit or specified
      at the block level. The less useful modes: ALLOW_8X8, ALLOW_16X16,
      etc. are removed.

      Temporarily disable simple_bwd_adapt · c002bdf6
      Yaowu Xu authored
      This allows time to investiage the bug related to issue#917, adn the
      experiment should be re-enabled after a proper fix is in place for
      the issue.
